aluminum welding please

11-02-2013, 06:50 PM

I am interested in a miller 211, the manufacturer states it WILL weld up to 3/8 aluminum with the spool gun, is this true my dealer says NO?
It is a 160 amp machine with I think a 100 amp spool gun, but miller claims it will do 3/8, you guys know, will it do that aluminum at 3/8 max?

That is the rating for a single pass weld. Pre heat, joint prep, and multiple passes can accomplish more if the operator knows what he/she is doing.

That said, I wouldn't buy a 211 with the spoolmate 100 and expect to blast 3/8 aluminum all day everyday. It's not made to handle that. If that is what you need, a 252/251 with a 30a would suite you better.

I definitely agree with Cgotto6, I work mostly with 1/4" thick materials so I always try to buy a machine that can double that. I almost never have to worry about duty cycle or running the machine too hard. As long as I have $$$ to do so lol.
